In the early stage of hypertension and coronary artery disease, the diastolic function of the ventricle will be limited and lead to a reduction in myocardial blood supply to the coronary artery, which requires regular follow-up. If patients with underlying heart disease are not actively treated, long-term will lead to impaired cardiac systolic function and patients will experience chest tightness and shortness of breath. Patients with hypertension and coronary artery disease are advised to take β-blockers, such as betalactam; ARB drugs, such as temisartan tablets; diuretics, such as dihydroketorolac, compound salvia tablets, and other drugs in a timely manner. To ensure blood pressure within normal range and myocardial blood supply, reduce heart load, inhibit ventricular remodeling, inhibit or delay the progression of cardiac insufficiency, patients with hypertension and coronary artery disease should pay attention to low salt and low fat diet in daily life.
